The density of water vapor at 100C is 1700 times lower than that of liquid water. That means that even steam that has 97% liquid by mass in it has a density 50 times less than water. You can't swim in that. Steam that is 90% liquid by mass is 99.4% vapor by volume. That means the density is about 200 times less than water. You see, density involves mass and volume, and very wet steam is still mostly vapor by volume. Think about that before you make ridiculous comments about buoyancy.
